What should I do if the bearing hole of the gearbox is too large? How to handle it?During maintenance, it was found that the bearing holes near the dryer side of the gearbox were worn unevenly, with some areas being deeper, reaching a maximum depth of about 10mm and an average of about 3mm. The bearing and shaft are fitted with a detachable sleeve. The bearing model is 22313, with a speed of 745r/min and a temperature not exceeding 90 ℃. Do you know how to deal with the problem of large bearing holes in the gearbox?
Sorei Carbon Nano Polymer Material is a high-tech nano new material generated through polymerization process from advanced materials such as aviation grade resin, nano inorganic materials, high-performance carbon materials, fibers, etc. The advantages of this material include high bonding strength, good comprehensive mechanical properties, corrosion resistance, easy molding, and processability. It is a good choice for dealing with the problem of large bearing holes in gearboxes. Next, let's take a look at the operational steps for engineers to handle the problem of large bearing holes in gearboxes.

1. Use oxygen acetylene to remove surface oil from the wear of gearbox bearing holes;
2. Use a polishing machine to polish the metal surface until the original color of the metal is exposed;
3. Clean the area to be repaired with anhydrous ethanol;
4. Mix the Sorel carbon nanopolymer material until it is uniformly blended without color difference;
5. Apply the mixed material evenly to the area to be repaired and wait for the material to solidify;
6. Remove excess materials and reinstall components.
